Cant hear my radio

You need at least 8 amp power supply

Hi, my name is John. Try a external speaker, plug it in the back of radio, turn the RF GAIN to MAX. Turn the SQUELCH all the way to left, make sure the select knob is on CB, and on AM...try all this and if that's does not do it, let me know, I will post other steps here,.... hope this was very helpful....

Where is the noise coming from? If it is coming from your wheels then it would be your wheel bearings. They can get so loud that you cant hear a thing inside your car due to vibration.

Does the needle move when you key? Is the MIC gain all the way to the right? I pose these as questions because there was not enough info....

You'll need to program the radio frequencies into your scanner before it will scan . For a list of frequencies in Anoka County CLICK HERE .
For specific programing instructions for your UNIDEN refer to your owner's manual. They will give you a step by step instruction on how to program the frequencies into your scanner memory (If you need a manual, CLICK HERE
...be sure to select the scanner option on their pull-down menu.
THEN when you have the radio frequencies stored into your scanner, you'll be able to press scan and away you go.
Be sure to adjust the squelch just high enough to eliminate the static...turn the squelch counterclockwise until you hear loud static, then turn Clockwise just enough to silence static...
Let us know if you still have trouble.

You really don't want to have a loud talk back. Its usually controlled by your mic gain. the louder it is, the louder your talk back is.

Talk back is used so you can her how your audio is being transmitted. It makes a lot of sense when you have echo. use it to hear you echo to make sure its not too much.

The problem with a loud talkback is, if it is too high, you will get feed back in your transmit.

You should leave it where it is.

Well mine, (760) has a external plug to be use with ears plug, the cord should be long enough and it should not interfere with drivings conditions, but it sound real good loud and clear. The other solution could be the matching on the fm radio station, it could be auto or manual, but they have to match in order to hear propperly.
Hope this will help

sounds like a wheel bearing,ask a local mechanic to confirm

here's a little trick you can try to find your phone.take a radio and put it up to the mouth piece of one of your other phones and turn it up loud. but not too loud. this phone should be on talk mode.walk thru each room of your house when it's quiet, and listen for the radio. if the phone is off the hook, you should hear the radio enough to find the phone.
let me know if it works.

Sounds like a bad or miswired mic. Try a new mic ( use the proper cobra mic ). If the problem still continues, check all the swiches on the front of the radio and make sure you don't have any cold solder joints ( broken lead to board connections ). Good Luck
